I've been getting the same connection issues as well, so I just went to the conf and added every node on the fallback list, and set maxconnections to 50 and noirc to 1. I feel bad for relying solely on the fallback nodes, but I don't know what else to do, I can't connect any other way. I also can't access bitcoin.org main site. (I've tried the site and the client via VPN as well, so it's gotta be something on my computer. I've checked the firewall and the router and everything is fine, but by god I still can't connect!!!)
